Another possibility to reconcile?

We have many Chillispot systems, but as I mentioned before,
combined, at the time it was approximately 14.
I was hoping that there would be some way to have checkrad do
that for us, but since DD-WRT runs Chillispot and not Coova, we don't have
access to a great utility Coova implemented which would be able to tell us
what sessions it has active at the time.
Since I wrote the email, I've learned more. It seems that the
DD-WRT units reboot daily as their version of "Garbage Collection". It
also seems that unlike Coova, the old Chilli did not send Accounting_On
when it booted, and Accounting_Off when it was shutting down. I have
to do some more log and file investigation, but I'm thinking that the
combination of those 2 issues is whats causing all the "dirty" sessions.
Since all the units send output to syslog, I'm thinking about
having syslog output to a perl program that parses all the lines and if
it sees the beginning of a DD-WRT reboot, it will forge an Accounting_On
packet (If that is possible. I'm not sure if I'll run into the same issue
I did with trying to run a radtest from the radius server with the IP
and secret for a remote unit).
I'll also see, but I'm sure it'll be pretty difficult, if I
can convince the DD-WRT people to port the Accounting_On/Off function,
and hopefully Coova itself!
